Case Study: Cleveni achieves 4x ad revenue and 90% more Help Center visits with Google AdMob

Cleveni grew revenue 4x with AdMob native ads and analytics for Firebase

Cleveni, a South Korea–based mobile app publisher known for the ClevCalc utility app, struggled with short sessions and low feature discovery that left its Help Center underused and banner ads underperforming. To boost engagement and monetization, Cleveni partnered with Google AdMob and used Google Analytics for Firebase tools to redesign ad formats and better promote in-app features.

Working with Google AdMob, Cleveni implemented redesigned native ads and used Firebase Remote Config and Messaging to A/B test creatives and send targeted push notifications to users who hadn’t visited the Help Center or made in‑app purchases. Within one month, ad revenue grew 4x (total revenue across ads and IAP +261%), impressions rose 28%, CTR increased 113%, and Help Center visits jumped 90%, all achieved quickly and without extra coding.
